Well here is one of those lessons toy can learn from someone else's (me) mistakes.
Not really mistake as much as not considering all options to look at things I may already own.

I noticed this morning the $19 HF point n shoot laser thermometer I have goes to 800 degree F. More than enough for lead.

But the good thing is, with the new thermometer that goes to 1000f, I can also use it to play around with trying to cast aluminium items at some stage in the future. As well as dedicated it to mostly lead.

Aluminum melts at a little over 1200 degrees

A few years back there was a small fad amongst survivalist of attempting to melt aluminum cans https://en.wikipedia.org/wiki/3004_aluminium_alloy to make things by casting .. depending on the use anything that would be under intermittent strain soon cracked or broke.. especially small parts https://en.wikipedia.org/wiki/Aluminium_alloy the problem being 3004 is 1) not made for casting and doesn't fill out sand casting well and 2% it easily work hardens like a twisted paper clip and breaks ..



a lot of anguish and gnashing of teeth from frustrated would be survivalists

The saddest part that you can get useable flat sheets of easy to work aluminum from cans to make all sorts of small containers or cut down cans to make scoops and containers with wire handles of bails or even pocket and rocket stoves spinner lures for fishing

speaking of fishing most folks don't seem to know this but, if you buy fish hooks in bulk the prices are a lot different from buying them is small packets at sporting goods stores

example http://www.jannsnetcraft.com/live-bait- ... hooks.aspx in this example brand name item good size for night crawlers 6 cents each http://www.jannsnetcraft.com/live-bait- ... hooks.aspx some beer can flash and a found feather and you have a lure

pays to shop around and you don't need to do the whole melting it down thingy to make real useful or artistic things from aluminum

Maybe it was just the folks I knew that got head locked into melting aluminum for melting's sake and couldn't really come up with anything actually appropriate for the alloys at hand and totally overlooked the power of tin snips and punches to make things like lanterns and candle holders

aluminum can usually be soldered if you prep it right and maybe use a few tricks there are no end of tips online

best way to gauge the best way to use scrap aluminum is to consider the original manufacturing process used to make what is now "scrap" to you, and to consider if any great amounts or heat were used or if the item was cold formed originally.

Aluminum has all sorts of alloys with different properties and uses https://en.wikipedia.org/wiki/Aluminium_alloy

just like steel http://zknives.com/knives/articles/knifesteelfaq.shtml

Well thats good to know. For some reason I was thinking aluminum melted around 900.

Ive seen some people have some luck with cast aluminum for making jewelry.

Ive sand casted silver, gold and some brass. They Turned​ out ok. Actually the most useful sand cast I ever made was years ago I cast a new hinge for my Acer laptop. Remember when laptop hinges use to break all the time? Well the brass cast hinge I made using the original stamped parts as a pattern , worked better than the OEM hinges.

Besides that I cast some jewelry, and my kids use to press little toys in Rio Grande casting sand they pack into Altoid tins, and Id pour brass or silver in. Some had really good detail for lack of work and detail we did with them.

I still have my vacuum caster, all the accessories and about 5 pounds of casting plaster left. Problem is my burn out over dont work anymore so not much I can do except wear the bell jar as a party hat.. Lol. Oh, and use the vacuum pump to pull down car ACs for full recharing if needed.

hmmm .. don't know about laptops or their hinges ..never had one... seriously. all I ever had once I graduated from an Atari 800 is a windows desktop of one version or another.. my needs are simple

But yeah.. you got it right about casting... I kept asking those guys what they were going to cast with those melted beer cans... "ingots" was all they could come up with, at least you can make toys, keeping in mind the you tube videos were aimed at preppers ( maybe just selling hotter than needed melters, I dunno.. never got the point of it) Critical survival toys that can't be carved from wood with a lot less work ( shortest book in the world).. funny part was they couldn't even scrap the aluminum anymore... they were stuck with their ingots .. once the scrap dealer can't identify where the aluminum is from, or what it once was, he can't be sure of the alloy.. and there is already tons of ruined useless worthless aluminum scrap that got poisoned by mixing alloys, making it fit for neither casting nor drawing. All they can do is re-refine, it killing any economic advantage of recycling.

i've got an ample source of 6061, but don't think i can temper it properly.
That could be interesting. Ive seen concrete poured in african ant mounts to map the tunnels..
